Check Digit Verification of cas no

The CAS Registry Mumber 31037-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,3 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31037-03:
(7*3)+(6*1)+(5*0)+(4*3)+(3*7)+(2*0)+(1*3)=63
63 % 10 = 3
So 31037-03-3 is a valid CAS Registry Number.

Preparation of heterocyclic amines by an oxidative amination of zinc organometallics mediated by CuI: A new oxidative cycloamination for the preparation of annulated indole derivatives

Kienle, Marcel,Wagner, Andreas J.,Dunst, Cora,Knochel, Paul

supporting information; experimental part, p. 517 - 523 (2011/10/09)

Functionalized heterocyclic zinc reagents are easily aminated by an oxidative amination reaction of zinc amidocuprates prepared from various lithium amides. For the oxidation step, PhI(OAc)2 proved to be the best reagent. The required heterocyc

REACTION OF 1-DIALKYLAMINO-1-BUTYN-3-ONES WITH HYDRAZINE AND SUBSTITUTED HYDRAZINES

Ostroumov, I. G.,Tsil'ko, A. E.,Maretina, I. A.,Petrov, A. A.

, p. 1467 - 1474 (2007/10/02)

A series of 1-dialkylmino-1-butyn-3-ones were obtained, and their reactions with hydrazine and its alkyl, aryl and unsymmetrical dialkyl derivatives were studied.The reactions with unsubstituted and monosubstituted hydrazones lead to the formation of heterocyclic compounds of the pyrazole series, while the monosubstituted hydrazines form two isomeric products.Unsymmetrical dimethylhydrazine adds at the C1-carbon atom with the formation of compounds containing an open structure.
